Nesting symbols may be ideal.
Crude example: http://www.heathrowe.com/edge/animateinnersymbol/
In this case its nothing more than two nested Symbols.
Main symbol called 'main', which houses both squares (red square is called 'inner'); animate from the top to a certain position for a duration of 1 second.
When the 1sec completse, the inner symbol begins; duration of two seconds; when that completes a trigger at the 3sec marker instructs the timeline to go to a Label called 'start'; and repeats/loops the inner animation until instructed otherwise.
As Darrell, I agree. You need to use symbols and animate the part with code where needed.
Both very helpful thankyou.
I had just figured it out as you replied lol.
I set up a lable at the start of the section I wanted to loop and then put a trigger at the end of the section.
Super - welcome aboard, by the way
Thanks for the welcome. I am just trying out the CC trial. £45 per month is a lot of money, but I suspect I will end up paying it. Been using CS2 for a rather long time.
Just out of interest how do I set my avatar on this forum? Went into profile but couldnt see anything.
